I thought about it some more and I think I might be able to generate
the indices on the fly as part of the monomial extraction so it might
not be necessary.

So if it's not needed for quadrature it can be part of the monomial
extraction. Otherwise, it seems pretty simple to make a transformer
for index renumbering.
